When crossing the rotating speed of target of rank 5, as long as being controlled in a manner of rotor 24 is self-braking.
MCU17 is when the rank according to rotating speed of target changes the rotating speed of rotor 24, according to the rotating speed of target of rotor 24
Change the duration of the 2nd state under mono pulse control.Thus, DC Brushless Motor control device 15 can be in pulse control
The rotating speed of the lower control rotor of system.In addition, the duration said here is the time to be changed according to the rotating speed of rotor 24, and
Do not refer to absolute time.Also, MCU17 is when changing the duration of the 2nd state, to change the 1st switch element without changing
The mode of 2nd switch element is controlled.
In addition, suction device 1 can also possess the battery of the action power as three-phase direct-current brushless motor 20.The battery
Such as can also be the secondary cells such as nickel-cadmium cell, nickel-hydrogen cell or lithium ion battery.It is logical in three-phase direct-current brushless motor 20

That is, control unit 16 controls turning for rotor 24 according to the dump energy for the secondary cell that electric power is supplied to three-phase direct-current brushless motor 20
Speed.
Specifically, in the case where the residual electricity of battery is less than defined threshold value, MCU1 reduces the target of rotor 24
Rotating speed controls the rotating speed of rotor 24.Defined threshold value can be to represent the value of specific residual electricity, or defined
Ratio.In this is one, it is specified that threshold value be defined ratio.Defined ratio is, for example, the 20% of the capacity of battery.Thus,
For DC Brushless Motor control device 15 in the case where the residual electricity of secondary cell is less, can extend suction device 1 can
Usage time.Also, in the case where the residual electricity of battery is less than defined threshold value, MCU17 can also enter to be about to target and turn
Speed remains other processing of setting etc..By so forming, DC Brushless Motor control device 15 is in the residual of secondary cell
In the case of staying electricity less, the up time of suction device 1 can be extended.
Also, MCU17 can also be more than defined threshold value to be also less than defined threshold value according to the residual electricity of battery
To switch over the control of the rotating speed of target of rotor 24.Specifically, it is more than defined threshold value in the residual electricity of battery
In the case of, MCU17 does not change the rotating speed of target of rotor 24 and controls the rotating speed of rotor 24.It is also, small in the residual electricity of battery
In the case of defined threshold value, MCU17 reduces the rotating speed of target of rotor 24 and controls the rotating speed of rotor 24.Pass through such structure
Into DC Brushless Motor control device 15 is able to maintain that rule in the case where the residual electricity of battery is more than defined threshold value
Fixed attraction, being capable of the over reach time in the case where the residual electricity of battery is less than defined threshold value.That is, direct current without
Brush controller for motor 15 can be carried out between such as power conservation mode and energy saver mode according to the residual electricity of battery
Switching.
Fig. 7 is the figure of one of the moving period for showing the position of magnetic pole that magnetic pole position detection part 25 is detected.MCU17 roots
The moving period of the position of magnetic pole detected according to magnetic pole position detection part 25 determines whether to obtain from magnetic pole position detection part 25
The signal of the expression position of magnetic pole of offer and as judging the signal of position of magnetic pole.In the figure, a cycle of electric angle
The required time changes according to the change of the rotating speed of rotor 24.Specifically, in the case where rotor 24 rotates at a high speed,
Time needed for a cycle of electric angle is shorter than the situation of low speed rotation.Also, as long as the pace of change of the rotating speed of rotor 24 exists
In prescribed limit, then the change of the time needed for a cycle of electric angle is also in prescribed limit.That is, as one, as long as
Rotated with the rotor 24 more than 20000 [r/m] left and right rotated at a high speed in the extremely short time of a few degree, then a week of electric angle
The change of time needed for phase will be minimum.Therefore, MCU17 can be pushed away by calculating the time needed for a cycle of electric angle
Time-amplitude needed for a cycle of electric angle breaking at the time of calculating after the extremely short time.That is, MCU17 energy
It is enough to infer the signal for being produced at which moment and representing position of magnetic pole.It is being inferred in the signal that MCU17 will represent position of magnetic pole
Electric angle a cycle needed for time-amplitude at the time of the caused signal determining for representing position of magnetic pole to be non-noise.
MCU17 judgements obtain the signal that is judged as non-noise expressions position of magnetic pole and as being used to judge the signal of position of magnetic pole.
Also, MCU17 is by outside the time-amplitude needed for a cycle in the electric angle being inferred in the signal for representing position of magnetic pole
The signal determining that position of magnetic pole is represented caused by moment is noise.MCU17 judges not being judged as the expression magnetic pole position of noise
The signal put obtains as judging the signal of position of magnetic pole.
Also, moving period and the rotor for the position of magnetic pole that MCU17 can also be detected according to magnetic pole position detection part 25
24 rotating speed of target and feedback control is carried out to the rotating speed of rotor 24.For example, MCU17 passes through two patterns shown in Fig. 8
In any action pattern acted.Fig. 8 is the figure for two patterns for illustrating MCU17.Two patterns are, for example,
Electric current keeps pattern and rotating speed to keep pattern.In the case where MCU17 pattern is electric current holding pattern, MCU17 passes through
Be respectively fed to winding 21, winding 22, winding 23 current value feedback and control the rotating speed of rotor 24.Specifically, pass through
Current sensor (not shown) detects to be supplied to winding 21, winding 22, the current value of winding 23.In this case, MCU17
The winding 21 that is detected according to current sensor, winding 22, winding 23 current value and target current value between difference and count
Calculate and be supplied to winding 21, winding 22, the current value of winding 23.Also, MCU17 supplies the electric current of the current value calculated
To winding 21, winding 22, winding 23.
Also, in the case where MCU17 pattern is rotating speed holding pattern, rotating speed that MCU17 passes through rotor 24
Feed back and control the rotating speed of rotor 24.Specifically, MCU17 is according to the position of magnetic pole detected by magnetic pole position detection part 25
Period of change and calculate the rotating speed of rotor 24.Also, between rotating speeds and rotating speed of target of the MCU17 according to the rotor 24 calculated
Difference and calculate and be supplied to winding 21, winding 22, the voltage waveform of winding 23.Also, the voltage that MCU17 will be calculated
The electric current of waveform is supplied to winding 21, winding 22, winding 23.In the movement for the position of magnetic pole that magnetic pole position detection part 25 is detected
In the case that the rotating speed of rotor 24 shown in cycle exceedes rotating speed of target corresponding with the operation that operation detection part is detected,
MCU17 carries out the control of these rotating speeds.That is, shown in the moving period of the position of magnetic pole detected in magnetic pole position detection part 25
In the case that the rotating speed of rotor 24 exceedes rotating speed of target corresponding with the operation that operation detection part is detected, control unit 16 is by turning
The feedback of the rotating speed of son 24 controls the rotating speed of rotor 24 by the feedback for the current value for being supplied to winding 21,22,23.
Thus, DC Brushless Motor control device 15 can suppress the rotating speed because of rotor 24 unexpectedly from being used as in target by feeding back
The rotating speed of target of limit value generates heat caused by rising.
Here, in this is one, the operation that operation detection part is detected is the grade for the attraction for selecting suction device
Operation.That is, the operation to suction device is the operation of the grade for the attraction for selecting suction device.As shown in fig. 6, in storage part
In, represent that the information of the rotating speed of target of rotor 24 is divided into the suction device 1 that the operation detected with operation detection part represents
